Problems solved by technology

This makes it impossible to fully control the temperature and dehumidification of the air blown in the room
Since the compressor is single and operates at a constant speed, it cannot fully control the dehumidification capacity according to the difference between the set humidity and the room humidity

Abstract

An air conditioner comprises a compressor, a first indoor heat exchanger, a second indoor heat exchanger and a dehumidifying restricting device, which is connected between the first indoor heat exchanger and the second indoor heat exchanger, and used as a restricting device in the dehumidifying operation, wherein the airflow speed of an indoor fan used for ventilating the first indoor heat exchanger and the second indoor heat exchanger, is variable in the dehumidifying operation. The air conditioner comprises: a function of setting the indoor fan as a low air flow speed operation or a high air flow rate speed operation; and a function of operating the compressor with a higher capacity in the high air flow rate speed than in the low air flow speed operation.

Description

[0001] This application is a divisional application of the application dated June 1, 1994, application number 02131692.9, and titled "air-conditioning equipment". technical field [0002] The present invention relates to an air conditioner and its operating method. More particularly, the present invention relates to an air conditioner and its operating method in which dehumidification operation can be performed with little cooling to little heating over a wide temperature range. Background technique [0003] As a conventional air conditioner in which a dehumidification operation is performed to reduce humidity, there is known a system in which air cooled by an evaporator is reheated by an electric heater; Heat of condensation reheats. When comparing these two systems with each other, especially from the point of view of energy saving, the latter is considered to be better because the former consumes a lot of power. [0004] In addition, in Japanese Patent Unexamined Public...
